120 output electric currents cut-off current) and output end cut-off current (i.e. the cut-off current of battery current) control in battery constant current
The current value in (Constant Current, CC) stage；It then is that battery 1102 charges by voltage transformation components 1101,
And pressure adjustment adaptor 120 is controlled by feedback regulation component 1103 and carries out output adjustment；Due to the output electricity of pressure adjustment adaptor 120
It forces down in cell voltage, so that the input terminal electric current (i.e. the output electric current of pressure adjustment adaptor 120) of voltage transformation components 1101 is first
Reach cut-off current, as the output voltage of pressure adjustment adaptor 120 continues to increase, battery current can also progressively reach cut-off current,
At this time stop increasing the output voltage of pressure adjustment adaptor 120, with being gradually increased for cell voltage, battery current can gradually subtract
It is small；When battery current is reduced to predetermined current threshold, at this time increase the output voltage of pressure adjustment adaptor 120 again, until electricity
The charging complete in pond 1102.Since the setting of current-limiting points can be increased in voltage transformation components 1101, and pass through in the prior art
The technical solution that power switch is directly filled is compared, due to increasing current-limiting points in voltage transformation components 1101, so that safety
It is higher.
